    finding the slope is simple. all we need to do is re-write the equation in terms of y and we'll go from there.

    so wouldn't it be -Y=5-8X?

    correct. One more step, let's get rid of the negative.

    we do that my multiplying both sides by -1 or divide both sides by -1

    -Y=5-8X --------- -1 ?

    when you divide an entire side, it means each term has to be divided.

    the general rule is that whenever and equation is in the form of y=mx + b m is the slope/gradient and b is the constant of y-intercept.

    A more mathematical term would be that the first derivative of an equation will tell you what is the slope. If y = mx + b then (dy/dx) = m

    the slope is 8, therefore it is going to the upper right since it is positive and it is steep

    hmm why not y = 8x-5?
